ST6G3237

ST6G3237 Dual supply level translator for SD/ MINISD / T-FLASH Features ■ High speed: – tPD = 4.4ns (Max.) at TA = 85°C – VCCB = 3.0V – VCCA = 2.3V Low power dissipation: – ICCA = ICCB = 5µA (Max.) at TA = 85°C Balanced propagation delays: – TPLH ≈ TPHL Power down protections on inputs and outputs 26Ω series resistor on A-Side Operating voltage range: – VCCA (OPR) = 1.4V to VCCB – VCCB (OPR) = 1.4V to 3.6V Latch-up performance exceeds 500mA (JESD17) ESD performance: – HBM > 2kV (MIL STD 883 method 3015); ROHS compliant for µTFBGA25 package µTFBGA25 TSSOP20 ■ ■ ■ ■ ■ Description The ST6G3237 is a dual supply low voltage CMOS Level Translator for SD/MiniSD/T-Flash fabricated with sub-micron silicon gate and fivelayer metal wiring C2MOS technology. Designed for use as an interface between a 3.3V bus and a 2.5V or 1.8V bus in a mixed 3.3V/1.8V, 3.3V/2.5V and 2.5V/1.8V supply systems, it achieves high speed operation while maintaining the CMOS low power dissipation. The A port is designed to track VCCA. The B port is designed to track VCCB. This IC is intended for two-way asynchronous communication between data buses and the direction of data transmission is determined by CMD-dir/DATA0-dir/DAT123-dir inputs. The B-port interfaces with the 3V bus, the A-port with the 2.5V and 1.8V bus. All inputs are equipped with protection circuits against static discharge, giving them ±2kV ESD immunity and transient excess voltage. ■ ■ ■ Order codes Part number ST6G3237TTR ST6G3237TBR Packa...
